Important Question: When Will Unopened Beauty Products Expire?

"Most face washes hold up about six to 12 months after their expiration dates suggest. That said, if the face wash has active ingredients in it (such as glycolic acids, peptides, or antioxidants), it will tend to have a shorter shelf life (around six months), as those ingredients are more unstable and may become ineffective. If there is no expiration date on the packaging, I would suggest using the product within one year of purchase to play it safe." — Dr. Elizabeth Tanzi
